Hands on science experiments are a great way to get preschool children to problem solve and explore their world.
The video below is an add-on science experiment for my winter unit. It shows children how matter changes from a liquid state into a solid form. What happens when you add salt to ice? How does the temperature affect the matter of an object?
If you add salt or sand on top of ice during the winter – how it can give you more traction. Plenty of teaching possibilities.
